10、(the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical comm

11、ittee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrote

12、chnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the memb

13、er bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifyi

14、ng any or all such patent rights. ISO 12643-5 was prepared by Technical Committee ISO/TC 130, Graphic technology. It is the intent of ISO/TC 130 that this first edition of ISO 12643-5 become applicable to new equipment manufactured from 2012-01-01. ISO 12643 consists of the following parts, under th

This part of ISO 12643 provides requirements for controls and for guarding residual hazards and ha

17、zards created by point of operation of manually fed and automatically fed platen presses. It also provides requirements specific to the use of a flywheel, and specifies safe operating practices and training requirements. During the development of this part of ISO 12643, existing relevant standards o

18、f other countries were taken into consideration. An effort has been made to harmonize the requirements of many countries, recognizing that national standards or laws may dictate national requirements. In cases where it was known that there is a national requirement that differs from this part of ISO

19、 12643, that has been noted. This part of ISO 12643 was developed to harmonize the following US and European safety standards: ANSI B65.5, Safety standard Stand-alone platen presses EN 1010-5, Safety of machinery Safety requirements for the design and construction of printing and paper converting ma

28、rms and definitions given in ISO 12643-1 and the following apply. 3.1 point of operation area of the press in which the process (such as die-cutting, embossing, foil stamping, printing, etc.) is being performed 3.2 protective device safeguard other than a guard EXAMPLE Examples include, but are not

29、limited to, hold-to-run controls, two-hand controls, ESPDs, etc. NOTE Adapted from ISO 12100. 3.3 stand-alone platen press self-contained machine not intended to be used as part of an integrated manufacturing system 3.4 trip bar protective bar that, when pushed, activates the interlocking safety sys

30、tem of the machine NOTE A trip bar can be a metal bar or a pressure-sensitive edge. 4 Safeguarding of significant hazards 4.1 General Safeguarding shall be provided in those areas where it is recognized that operators are exposed to significant hazards. The guarding requirements of ISO 12643-1 apply

31、. Guard construction shall meet the requirements of ISO 14120. All platen presses shall have trip bars (see 4.4) or other protective devices (see 4.5) located where access to a hazard is possible. 4.2 Additional safeguarding requirements On machines wider than 1,6 m, the impact hazard created by the

32、 movable platen while opening shall be guarded by the use of a knee bar (see Figure 1, Item 7). The length of the knee bar shall be equal to or greater than the width of the movable platen. The knee bar shall be constructed such that it will retain its shape to ensure actuation of the trip function

33、throughout its length. With the movable platen in the open position, the clearance between the knee bar and front surface of the movable platen shall be at least 120 mm. See Figure 1. All trip bars shall be provided with a switch mounted on each end of the trip bar. The signals of the switches alloc

34、ated to the individual trip device shall be processed separately. The conductor cables connecting the switches shall be physically separated and shall be located outside the electrical cabinet. Trip functions using mechanical devices (including knee bars) shall satisfy the requirements of ISO 13856-

35、2 and PL re of ISO 13849-1 or SIL3 of IEC 62061. Trip functions or presence-sensing functions using laser scanners shall satisfy the requirements of PL rd of ISO 13849-1 or SIL2 of IEC 62061. The safety system that controls trip devices and their related signal processing, which safeguard routine an

36、d regular access to a hazard point on a manually fed device, shall comply with PL re of ISO 13849-1 or SIL3 of IEC 62061. ISO 12643-5:2010(E) ISO 2010 All rights reserved 34.3 Safeguarding side access Various means may be used to prevent access from the sides of the press. These means include, but a

37、re not limited to, the following measures. a) Fixed protective barriers, interlocking guards and/or interlocking tables that prevent access, from any side of the press, to areas of significant hazard not otherwise guarded in accordance with this part of ISO 12643. If interlocking tables are used, ta

38、bles shall extend 1 000 mm from the side frame outward and over the length of the press, reaching from the front edge of the open position of the movable platen to at least 250 mm behind the backward edge of the trip device. See Figure 1. b) Laser scanners meeting the requirements of 4.5, provided o

39、n both sides of the platen, with the scanned area being at a distance of 200 mm minimum and 250 mm maximum (measured from the beginning of the scanned area). The size and shape of the scanned areas on the sides shall be as shown in Figure 2 a). Access from the front and rear of the platen press to h

40、azards between the laser scanners and the machine housing shall be prevented by fixed guards see Figure 2 b). Means of preventing access to the hazard zone between the movable platen and the punching plane, other than those defined in a) or b) above, shall provide an equivalent level of protection.

43、y fed platen presses For manually fed machines, one of the following configurations shall be provided. a) When the press is less than 1 m wide, an interlocked protective device (U-shaped trip bar) that covers both the sides and the top of the point of operation shall be provided (see Figure 1 and Fi

44、gure 3). The platen trip bar shall pass under the U-shaped trip bar in its operating position with a maximum clearance of 12 mm (see Figure 4). The minimum distance shall be maintained throughout the range of all operating temperatures. If the stopping distance specified by the manufacturer is excee

45、ded, the control system shall prevent an additional cycle until the brake/clutch system is adjusted. This requirement shall be met at all speeds of the machine. The stopping distance shall be monitored at the end of each cycle. NOTE A cycle begins in the stopped position and is completed when the pl

46、aten returns to the stopped position. The U-shaped trip bar pivot shall be rated such that a force of 20 N is sufficient for actuation and triggering of the clutch/brake device. The pivot of the U-shaped trip bar shall be below the punching plane (see Figure 5). ISO 12643-5:2010(E) ISO 2010 All righ

47、ts reserved 5For manually fed machines operated in the automatic (timer-controlled) mode, an additional trip bar, usually located on the top edge of the movable platen, shall also be provided. This trip bar, when actuated, shall stop platen motion. b) For machines greater than 1 m wide, a presence-s

48、ensing device that will detect the presence of a person on the moveable platen. If a person is detected, start-up shall be prevented. c) A laser scanner mounted on the top of the fixed platen (see Figure 2) and meeting the requirements of 4.5.
